[PATCH 0/4] iopoll fixes + cleanups

[Pavel Begunkov]

[1] fixes a recent for-stable patch, should be for stable as well.
[2] fixes getting mm from a wrong task in iopoll path.

[3,4] are unrelated cleanups. I don't send them separately because
they may conflict.

Pavel Begunkov (4):
  io_uring: fix hanging iopoll in case of -EAGAIN
  io_uring: handle EAGAIN iopoll
  io-wq: compact io-wq flags numbers
  io-wq: return next work from ->do_work() directly
